Raunak Dey
Graduate Student (GTA)
Education

BS-MS in Physical Sciences (2015-2020) from Indian Institute of Science Education and Research Kolkata (IISER K).

Research Interests

I am interested in Experimental Soft Matter and Biophysics. I have been using Optics based tools to probe the motion of particles in simple and complex fluids. I plan to pursue my Ph.D. in a similar direction. Take a look at my webpage to have a better understanding of my past work(s).

I used to work with Optical Tweezers during my MS in India. I looked at problems from stochastic dynamics of Brownian particles, to correlated motion in viscoelastic media. Recently I have started working on non-equilibrium aspects of driven particles where we are studying fundamental results derived from stochastic thermodynamics.
